These Food Preservatives are Linked to Cancer

A new study published in The BMJ adds to growing evidence linking certain food preservatives commonly found in processed foods to increased cancer risk. Analyzing dietary and health data from more than 105,000 participants over 14 years, researchers found higher cancer incidence associated with additives such as sodium nitrite, potassium nitrate, sulfites, and sorbates—ingredients frequently used in processed meats, refined grains, cereals, and alcoholic beverages.

While the observational study does not establish causation, the findings align with longstanding research on processed foods and cancer. The authors urge further evaluation of preservatives currently considered “generally recognized as safe” and emphasize the public health value of promoting minimally processed foods.
